HOSE CLAMP.

" Application filed December 10,1923. Serial No. 679,622.

Tacit whomit" may concern: I r

Be it known that L'WILLIAM T. RUTLEDGE,

a citizen of the United States, residing at Santa And, in the county of Orange and State of California, have invented new and useful Improvements in Hose Clamps, of

' I shown until the device is assembled. Not

which the following isa specification.

Th1s invention relates to clamping devices andmore particularly to that class of clamp-' ing devices which are-employed for connect ing the ends of'tube or hose, or in connecting the s-Ame to nipples for :thepurpose of forming, for example, a: communication be; tween a radiator and the water. jacket .ofa gasoline engine. r

An ob ect of my present invention is. to

provide a clamp of the above character:

which is simple and economical and which may be quickly clamped and unclamped.

Anotherobject isthe provision of acla-mp which may be adjusted without employing a nut and bolt. g

" A further object of this invention is to provide a clamp whichis not likely to catch or pinch the-hose and thereby interfere with its proper positioning and tightening.

Other objects will be appreciated upon reading; the following specification.

The invention is illustrated in the accompanying drawings, in which Figure 1 is an elevational View, partly in section, illustrating the clamp as formed from a single band or ribbon, and means for fastening the same. p

Figure 2 is anend View of Figure l.

Figure 3 is an elevationalvi'ew,partly in section, of a modified form of my invention,

in which two strips or bands'are employed to form the tube-enclosing ring.

Figure l is a side view of Figure 3.

Figure 5 is still another modification of my invention, in which the tube-enclosing ring is formed with one'length of ribbon, but in which both end portions are cut away, the remaining end portions being disposed adjacent each other and extending in opposite directions and forming tongues which form a closed ring. Figure 6 is an end view of Figure 5.

In carrying out my invention as illustrated in Figure 1 and 2, I may employ a single length of ribbon 8, having, for example, four perforations 9,10, 11, and 12' made therein, two near each end. One end portion of the ribbon 8 may be bent at an angle at the point 13 and it may be bent again at the point I let, and doubled back on itself forming a :fold 15 and in such manner that the perforations 9 and 10 coincide with each other; The same end portion may be. again bent to form a loop 16 which,

however, should not be closed so much as.

far froin the other end of the ribbon 8, the latter may be bent at an angle-at17 and again at 18' and doubled back onitslef to form a vfold 19, so that the perforations 11 and 12 coincide, and may then be bent again at 20 beyondwhich point-extends a tongue 21. .The ribbon 8 may then be formedinto a ring as shown in'Figure 1, the end portionof the tongue 21-underlapping the other end of the-"circular vpart of the ribbon ,8, thus serving to'bridge' the gap between the folds 15 and 19;

A cotter pin 22 may be passed through the perforations 9, 10, 11, 12, after which the end of the loop 16 may be pressed down tolthe position shown in order to hold the head 23of the cotter pin securely and thereby prevent the'separation of the cotter in from the ring, thus avoiding the .proba 1e loss of the cotter pin.

For the purpose ofclamping on a hose, for example, the fold 19'may be' withdrawn from the lower end at of the cotter pin, thus allowing the device to be placedover the hose, after which the fold 19 may be passed'around the end 24 of the cotter pin. The ring may then be tightened around the hose by bringing together with a pliers or other means the folds 15 and 19 until the desired tightness is attained, whereupon the parts of the cotter pin maybe oppositely bent and the folds of the clamp thereby secured to each other, and the clamp secured to the hose.

Figure 3 is of similar construction to ing feature of this form of my invention,

Figure 3 also differs from Fig a single band or'ribbon. The differentiat- I however, lies in the fact that there are provided two tongues, 31 and 32, respectively, which extend in opposite directions. These tongues 31 and 32 consist each of onc'half of the width of the band or ribbon, being so formed by cutting away one-half of the width of the ribbon throughout their length. It Will of course be appreciated that such a structure or some modification thereof is necessary in order that the tongues may pass each other in opposite directions. It will be seen that in order to effect such arrangement of the tongues the bend Lit will have to be made in a direction opposite to that-shown in Figure l.

While I have described a plurality of forms of my invention, it is evident that other modifications than those described may be readily contrived, which, however, employ the same underlyin principle. For example, the folds or double layers mentionedin the specification are not essential in all forms of my invention, but are sometimesusedin'order to give additional rigidity. I therefore desire it to be understood that such modifications coine within the scope of this invention.

1 claim 1. A hose clamp comprising a single length of ribbon bent 'into a ring, a portion adjacent one end of said ribbon beingbent outward from the ring and bent back on itself to form a fold which is perforated, an extension beyond said fold to form a loop, a portion of the ribbon adjaoent its other end bent outward and back on itself to form '-aperforated fold, an extension beyond the latter fold forming a tongue which bridges the gap between said folds, and fastening means passing through said perforations, one end of said means being secured within said loop.

2. A hose clamp comprising a single length of ribbon bent into a ring, a portion adjacent one end of the ribbon being bent outwardly from the ring and bent back on itself to form a fold which is perforated, an extension beyond said fold bent to form a loop, a portion of the ribbon adjacent its other end bent outwardly and back on itself to form a perforated fold, an extension be yond the latter fold forming a tongue which bridges the gaps between said folds, and a cotter pin passing through said perforations, one end of said cotter pin being secured within'said loop.

3. A'hose clamp comprising a single length of ribbon bent into a ring, a portion adjacent one end of said ribbon being bent outward from the ring and bent back on it self toward the outer periphery of to form a fold which is perforatethihaving an extension adapted to be bent upwardly away from the ring, a portion of the ribbon adjacent its other end being bent outward and back on itself to form a fold which is perforated, an extensiononsaid ribbon forming a tongue adapted to bridge the gap between said folds, and a cotter pin adapted to pass through the perforated folds for effecting a connection therebetween.
